摘要

本文通过将聚合物分散液晶膜包裹在固定曲率半径的聚对苯二甲酸乙二醇酯（Polyethylene terephthalate，PET）软膜内，通过平面波干涉的全息技术，制作了一种柔性曲面全息光栅。文章研究了柔性曲面全息光栅的衍射再现特性。使用微元法以及耦合波理论研究推导了柔性曲面光栅在曲率改变时的衍射特性公式。提出以柱面波再现曲率变化时的柔性全息光栅，以实现最佳衍射效果再现，论文推演了相关技术参数，如柱面波焦点位置，柱透镜焦距与衍射横向放大关系率等。在曝光时间为70 s和曝光强度为30 mW/cm

的条件下，制备了中心衍射效率为88%的柔性光栅。实验通过改变柔性光栅的曲率半径和使用柱面波再现，实现了理论计算的衍射横向放大率特性。

Abstract

In this paper

a flexible curved holographic grating is fabricated by wrapping a polymer dispersed liquid crystal film in a polyethylene terephthalate (PET) film with a fixed radius of curvature

and using plane wave interference holographic technology.The article studies the diffraction and reproduction characteristics of flexible curved holographic gratings.The article use the microelement method and coupled wave theory to derive the diffraction characteristic formula of the curved flexible grating when the curvature changes.A flexible holographic grating with a cylindrical wave to reproduce the curvature change is proposed to achieve the best reproduction of the diffraction effect. The paper deduces the relevant technical parameters

such as the focal position of the cylindrical wave

the focal length of the cylindrical lens and the relationship between the lateral magnification of diffraction and so on. A flexible grating with a central diffraction efficiency of 88% was prepared under the conditions of an exposure time of 70 s and an exposure intensity of 30 mW/cm

. The experiment achieved the theoretically calculated lateral magnification characteristics by changing the radius of curvature of the flexible grating and using cylindrical wave reproduction.
